I'm concerned this could cause more bottlenecks and accidents at the Broadview and Castle Frank intersections, which are already danger zones for pedestrians.
I can't see any basis for that at the Broadview intersection.
The change I'm suggesting wouldn't increase total volumes of traffic, it would shift, one stream of traffic back to Castlefrank.
Certainly, that intersection would see an uptick in volumes, primarily in the PM peak.
But it would have to be redesigned anyway.
I think hardening the corners (reduced turning radii) on the north side, and introducing a crosswalk on the west side would serve to create a more amenable intersection for pedestrians.
I would also remove the current mid-block turn channel east of Castlefrank in any design, further augmenting safety.
As a busy intersection it will always have safety challenges.
But I don't think a modest uptick in volume for 3-hours a day is nearly the scale of issue of the existing on-ramp.
Also, if the on-ramp is removed, the entire 3rd lane of Eastbound traffic can be eliminated east of Castlefrank (its there to serve the on-ramp).
That could allow better quality separation for the bike lanes, and wider sidewalks across and on the approach to the viaduct.
I should add, the City is looking at removing the connection to Bayview Avenue, which would also help offset any volume of traffic increase connecting to the DVP.
